Gas Pressure; High Altitude Adjustment - Jøtul GF 400 DV IPI Sebago Installation And Operation Instructions Manual

Gas Pressure

Correct gas pressure is essential for efficient and
safe operation of the GF 400 DV IPI gas stove. It is
important that the correct pressure is established
at the time of the installation. Proper gas pressure
provides a consistent flow of gas to the appliance and
is instrumental in checking for gas leaks.
Pressure Test: Attach a manometer to the
appropriate test point on the valve. See fig. 26. The
gauge connections are located on the front of the valve.
Connections are identified by:
E - for Inlet or Supply Pressure (the amount of gas
coming to the valve.)
A - for Manifold Pressure (the amount of gas that
is coming out of the valve to the burner.)
ALWAYS TEST PRESSURES WITH VALVE CONTROL
KNOB SET ON HIGH.

The appliance and its appliance main gas valve
must be disconnected from the gas supply piping
system during any pressure testing on that system
at test pressures in excess of 1/2 psig (3.5 kPa).
The appliance must be isolated from the gas
supply line by closing its individual manual gas
shut-off valve (gas cock) during any pressure testing
of the gas supply piping system that is equal to or
less than 1/2 psig (3.5 kPa).

High Altitude Adjustment

LP Kit #157613
NG Kit #157614
The decreased atmospheric pressure of higher alti-
tudes affects heat value of gaseous fuels. Most gas
suppliers derate the gas intended for use at eleva-
tions above 2000 feet. Check with your gas supplier
before performing derate adjustment to the burner.
This appliance may be adjusted for altitude over
2000 ft. (610 - 1371 m) for propane or natural gas.
If the gas supplier does not derate fuels, install High
Altitude Adjustment Kit 157613 for propane gas or Kit
157614 for natural gas.
U.S & Canada per ANSI Z21.88-2009 • CSA 2.33-2009,

See data plate for additional information. For high
altitude installations consult the local gas distributor
or the authority having jurisdiction for proper rating
methods. If the installer must convert the unit to
adjust for varying altitudes, the information label
must be filled out and applied to the appliance at the
time of the conversion.
Cet appareil est equippé pour gaz naturel des
altitudes compries entre 0 et 4500 pieds (0-1372 m )
seulement.
Derating Procedure
• Follow Steps 1-8 of the Fuel Conversion procedure
on page 16 to change the burner injector. Use the
injector supplied with the adjustment kit. De-
tailed instructions are also included in the kit.
• Conduct gas leak and gas pressure tests as de-
tailed on this page.
• Conduct system check and flame picture adjust-
ments as specified on pages 23 and 24.
INSTALLER: Fill out the appropriate information
and apply the high altitude conversion label pro-
vided to the rating plate on the appliance. See fig. 27.
